A Wise Way to Make Families Rules
All groups, of whatever size or nature, need standard operating procedures. Without them, groups may very well fall into confusion, chaos and conflict. The functions that rules can serve are indispensable. When it comes to parenting, making rules can make a big difference in our family as well. Actually, the issue is not whether our families need rules. We do need them. The real issue is how to motivate all family members to comply with (遵守) them.
At some time in our lives we all have felt unmotivated to comply with some rule or policy that we had no voice in making. Denied the opportunity to participate in establishing a rule, most people feel imposed upon and resentful of the new rule. But when people actively participate in setting a rule or making a decision that will affect them, they are more highly motivated to comply with it. We call this the Principle of Participation, and it has proven its effectiveness in families as well.
When children are given the opportunity to participate in setting rules or making decisions that will affect them, several good things happen. Children feel better about themselves — having more self-esteem (自尊心) and self-confidence. Such a good effect is due to their feeling that they have gained more “fate control” over their own lives. They also feel they are equal members of the family with an equal voice in making decisions and establishing rules — they’re part of a team, not second-class citizens. This means that families that function collaboratively and democratically will have closer and warmer relationships than those in which the adults act as bosses or authorities expecting the children to obey the rules made for them.
Another important reason for encouraging the full participation of family members in decision making is that it often produces higher-quality solutions to problems. Two heads (or three, or four) are better than one. Shared decisions will be based not only on the knowledge and experience of the adults but also on those of the children. The admonition (告诫) that father knows best should be challenged now.

A previously unlit cycle path in the Netherlands has recently drawn our attention. It has been resurfaced with a material that consists of thousands of shining stones in order to create a well-lit route. The Van Gogh Path, so called after the artist who lived in the town of Nuenen in 1883, combines the traditional with the contemporary in a gesture that acknowledge ledges Van Gingh’ masterpiece The Starry Night, but also shows the way ahead for city lighting. The Van Gogh Path is not a single case; it is not difficult to foresee a time when natural materials could help light the cities of the future.
Why should we care about city lighting? What’s wrong with current electrical city lighting anyway? Well, the problem that it causes is two-fold. First, of course, electrical lighting in most cities comes from non-renewable resources. According to the International Energy Agency, almost 20% of global electricity is consumed for lighting, which is responsible for high levels of carbon emissions. But there’s also the belief that electrical light itself is a form of pollution by destroying our view of the night sky.
From the above reasons, then, it seems wise to investigate other approaches. The city of Glasgow is attempting to use intelligent street lighting to monitor how citizens interact with the urban landscape and minimize electrical consumption and thus emissions. This “Smart City approach” is seen by many as the way of the future, but some designers aren’t convinced. They are pioneering the altogether more original approach of using materials from the natural world in order to replace electrical light entirely. They believe that this new “technology” can one day completely replace microchips and digital systems as we find better ways of making use of the light-producing mechanisms (制) that already exist in the natural world.

More devices like the iPhone, iPad and Kindle produce a blue light that causes our sleep to be restless and disturbed, according to a new study.
The study was led by Dr Paul Gringras, a sleep disorder specialist at a children's hospital in London. Together with her colleagues, Gringras found that manufacturers have started making bigger, brighter, bluer screens in an effort to increase the efficiency of our screens during daytime.But, as an unwanted byproduct, this light is affecting our sleep and productivity.
The study said that this type of light is likely to cause the most disturbance to sleep, as it most effectively overpowers melatonin (褪黑素). a hormone①that reminds us to sleep every night. Besides, using our devices before bedtime could even affect our performance during the day, because exposure to this blue light changes our body's natural rhythms.
“The development of light-producing devices means that for many people, a 'book at bedtime'is now often an‘e-book’,” Gringras pointed out.“Reading a traditional paper book by the light of your bedside lamp doesn't affect your sleep, because bulbs produce a yellow-red light. In comparison, the same book read in electronic arrangement will provide a very different light signal with biological effects.”
The researchers called on all device manufacturers to adjust screen lighting for the sake of the users’sleep quality and overall health.“All hardware devices should have an automatic “bedtime mode”that shifts blue and green light production to yellow and red as well as reduces backlight/light intensity,” Gringras said.
“And, we hope that as technology improves, more and more people will realize that‘brighter’will not always be equal to‘better’,”the researchers concluded.

If you’re one of those people who has trouble falling asleep, listen up. You might fall asleep 15 minutes earlier and wake up far less during the night if you put on a pair of socks at bedtime.
To understand why you first need to grasp the relationship between core body temperature and sleep. During daylight hours, the human body hums along at an average temperature of 98.6 degrees Fahrenheit (37 degrees Celsius). But at night, your core body temperature dips as much as 2 degrees Fahrenheit (1.2 degrees Celsius) over the course of six or seven hours of sleep.
This gradual decrease in core body temperature, as it turns out, is a key part of the complicated neurobiological (神经生物学) dance of falling asleep and staying asleep. And the faster you can lower the core body temperature, the faster you will fall asleep. Researchers have show that warming the feet before going to sleep using a warm feet bath or by wearing socks promotes vasodilation (血管扩张), which in turn lowers the body’s core temperature faster than going to sleep with cold, bare feet.
Scientists suppose that socked feet have a neurological effect as well. Inside the brain’s “thermostat (恒湿器)” is a type of neuron called a warm-sensitive neuron (WSN) that increases its firing rate when there’s a temperature difference between the body’s core temperature and extremities like the feet. Research has shown that WSN firing rates go way up on the beginning or slow wave or deep sleep and gradually decrease prior to waking up. So WSNs may play a role in generating the sensation of sleepiness that helps us fall asleep and stay asleep. And if that is the case, warming up the feet before bed time gives WSNs an extra power.
In a small study, researchers found that wearing a pair of special sleeping socks not only sped up the beginning of sleep, but increased overall sleep time by an average of 30 minutes and cut nighttime waking periods in half.
If you are worried about becoming too warm while wearing socks in bed, look for ones made of natural breathable fibers.

Many distance learners agree that the most difficult part of studying online is staying motivated. Because students must take the initiative to complete their courses completely on their own, without the physical presence of teachers and other peers, many students find it easy to become distracted and discouraged in their work. Don’t let this happen to you-plan ways for yourself to stay motivated before you’re tempted to stray from your books. Use the following motivational tips to stay on task.
Find a friend or relative who has similar interests or who would enjoy hearing about your studies and let them know what’s going on in your classes. You’ll understand the material better when you have a chance to explain it out loud and will be motivated to stay on task in order to keep up with the conversation.
Don’t rely on campus consultant; design your own map of completed classes and post it somewhere that is visible daily. There’s a certain satisfaction that comes with watching your goals be accomplished. When times get hard, you can always turn to your chart and see how far you’ve come.
You get rewarded for good credit and safe driving. Why shouldn’t you reward yourself for doing well in your coursework? Whether it be a night on the town, a new dress, or even a new car, setting up a reward system just may be the extra push you need to succeed. If you stick to your system, you may find yourself pleasantly surprised.

Though the risk of crowd crush is rare, it can be deadly when it happens. Crowd crush occurs when many people are packed together and begin to fall over one another. In the past, such instances have caused horrible injury and even death. To avoid such a fate, it’s best to escape the crush before it happens.
Before attending a crowded event, look up a map of the venue. This will give you an idea of the surroundings - pay special attention to any exits. Once you arrive, choosing the right spot can be crucial. Avoid the middle or front; instead, pick the back or edges of a crowd. It’s also important to trust your feelings. Stay aware to see if you feel packed in at any point. The more crowded the event becomes, the sooner you may need to retreat to a safe place.
If you do end up in a crush, here’s how you can stay safe. The most important thing you can do is stay on your feet. To do this, spread your feet apart and bend your knees a little. Also make sure to move with the flow of the crowd. Trying to move against a crowd of people will only end in disaster.
Helping others is another great way to keep everyone safe. Once one person falls down, more people tend to fall over them. So if your neighbor in the crowd falls to the ground, help them up.
A common cause of death in a crowd crush isn’t being crushed but rather losing air. It’s best to hold out your arms in front of your chest. This allows space between you and the person in front of you. It also protects your chest and lungs from being crushed on the ground should you fall.
There is usually fun where the crowds are, so enjoy yourself. But remember to stay alert!
___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Why Willing to Wait?
First it was the fried chicken. Then a variety of fancy milkshakes. No matter what time it is or how bad the streets smell, there are plenty of people waiting in line for hours to get their hands on the food that everyone’s talking about. If you are not the type of person crazy for trendy foods, you probably wonder why someone would like to wait in a long line just to get a taste of a popular cream tea. There is a bit of psychology behind the craze of waiting before getting one’s chopsticks on a trendy food.
People are born curiosity hunters, especially for fresh ideas, according to some experts. At the sight of a long waiting line, they just can’t help having a try. And when the trendy foods are novel in looks and favors, even innovative in their sales environment, the desire for them is upgraded. All those stimulate people to investigate more—to deal with their curiosity.
In addition, having access to something that is sought out but hard to possess equips people with a feeling that improves their self-definitions. When someone is envied due to something he gained with efforts, his self-worth gets enhanced. Although it is yet to be determined whether the number of likes he receives on the photos of foods he’s posted online is connected with the level of envy from on-lookers, that feeling automatically becomes stronger.
Even more, “mob psychology” comes into play: when many people are doing something—waiting in line for the sought-after milkshakes, for instance —others are eager to be part of the group and share such a type of social familiarity, kind of like the natural pursuit of a sense of belonging. Tasting the same wait-worthy food has something in common.

People joke that someone suffering from paranoia (妄想症) sees danger everywhere, thinking someone is out to get him. In the case of microplastics, you don’t need to have paranoia to be worried about them being everywhere, because they basically are!
What exactly are microplastics? They are particles (颗粒) of any type of plastic that are less than 5 millimeters in diameter (直径). They have resulted from the plastic pollution widespread in the world today.
When plastic is exposed to environmental forces, it breaks down into these tiny particles, which, in turn, do not disappear but continue to exist for hundreds or even thousands of years. Every piece of plastic that has ever been made is still on Earth today, except for what has been burned. Often mistaken for food, plastics and microplastics in oceans and on beaches are often consumed by marine animals, which is harmful. Research has linked microplastics to cancer and other problems in animals.
Whatever you think about these particles, taking them in is easier than you think. When you heat food in a plastic dish in the microwave, microplastics get into your food. The water from a plastic water bottle contains the particles as well. After taking surveys of microplastics in air, water and seafood, scientists estimate that people may easily be eating 5 grams of plastic a week. Researchers don’t know yet if or how this will affect humans. Microplastics have been found in human tissue samples, and no one yet knows how long they stay in the human body or what problems may arise.
Not until the amount of plastic waste in the world is reduced will microplastics decrease. So, while the evidence is still missing of the effect microplastics have on people’s health, reusing and recycling plastic is a no-brainer.

We all get a sensation when a song, for no apparent reason, refuses to leave your head — in fact we’re no strangers to the dreaded “ear-worm.” But a new study published in Psychology of Aesthetics, Creativity and the Arts reveals a fascinating insight into ear-worms, and why some songs are better than others in sticking in our heads by investigating the actual elements of the song that make it catchy in the first place.
To do this, most frequent ear-worms of the participants were entered into a database and compared to songs that had never been reported as an ear-worm at all. The melodic features of the tunes were then analyzed, revealing that ear-worm tunes were typically those songs that have overall melodic shapes common in Western pop music. A classic example of a common contour (音调的升降曲线) pattern is heard in Twinkle, Twinkle Little Star, where the first phrase rises in pitch and the second falls. This makes the tune easy to remember and has been exploited in many other nursery rhymes, but also in pop music.
In addition to the melodic shape, the other ingredient to the ear-worm formula is the unusual interval structure. The aim of this is to surpass the listener’s expectations of an average pop song, showing unexpected leaps or more repeated notes than usual. “Our findings show that you can, to some extent, predict which songs are going to get stuck in people’s heads based on the song’s melodic content,” says one of the researchers, “This could help song-writers or advertisers write a jingle (短歌) everyone will remember for days or months afterwards.”
The authors conclude that studies of ear-worms can help explain how the brain works, and improve our understanding in how perception, emotions, memory and spontaneous thoughts behave in different people.
___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________It Takes at Least 200 Hours to Make a Close Friendship, and More to Maintain It
Many of us worry that we don’t put in enough time to maintain close friendships. But how much is enough? Unfortunately, there’s no magic formula (公式) for how much time you need to spend on your friends to keep them. Each friendship and friend are unique and develops or ends depending on how we interact.
Forming a friendship in the first place takes a certain number of hours of being together. We need between 40 and 60 hours together for a person we know slightly to become a casual friend. In order to move from casual friends to close friends, we need to spend an additional 140 to 160 hours together for a total of about 200 hours.
However, deeper interactions can quicken that timeline. We can form a close bond in less than 200 hours with meaningful conversations. Contrarily, spending 200 hours together doesn’t necessarily mean a person will become a close friend. They have to want to be your friends. Some co-workers can spend 300 hours together and never become close friends.
When it comes to maintaining friendships, it’s not just the number of hours spent together, but what we do that matters. Engaging in passive activity with friends — like watching a TV series — is fun and enjoyable, but it doesn’t do as much to maintain friendship as having deep conversations, sharing feelings, and being a good listener. And routinely checking in with people we choose to connect with, through calls and texts or in person, helps maintain relationships and leads to higher scores of positive feelings, like happiness.
The key point is that sharing things about ourselves can lead to close friendships. Once that closeness is established, some ways to maintain closeness are supporting friends when things go wrong for them and celebrating their achievements.
